[Interest] Dynamic translation

[Graham Labdon]

Hi 
My Qt application supports dynamic translation IE the user can change languages whilst the application is running

Now I have a need to find the English equivalent of a translated string and don't seem to be able to find a way 

For example
Given QString s = tr("Hello");
I need to be able to get "Hello" from s after translation has taken place.

Has anyone done this before or have any ideas on how (if) it can be achieved

Thanks
